Embodiment 1

[0036] According to the raw material composition and parts by weight in Example 1 in Table 1, 1.2 parts of silane coupling agent Si-603 was added to 25 parts of thermosetting phenolic resin liquid, stirred evenly, and placed for later use. Take 0.5 part of toughening agent polyvinyl butyral and dissolve it in 2 parts of alcohol, fully dissolve it for later use. Then add 80 parts of alcohol into the large mixer, start the mixer to stir, add 90 parts of thermoplastic phenolic resin, stir for about 3 hours, add the prepared thermosetting phenolic resin solution containing coupling agent, and add the prepared Toughening agent and 0.5 parts of plasticizer dibutyl phthalate. After stirring for 3 hours, add 3 parts of curing agent urotropine, rinse the container used above with 3 parts of alcohol, add a stirrer and continue stirring for 4 hours, discharge the material into a barrel and seal it, and obtain an adhesive for grinding wheel mesh.

Embodiment 2

[0038] According to the raw material composition and parts by weight in Table 1, Example 2, 1.2 parts of silane coupling agent DL-602 was added to 30 parts of thermosetting phenolic resin liquid, stirred evenly, and placed for later use. Take 0.8 parts of toughening agent epoxy resin and dissolve it in 4 parts of alcohol, and fully dissolve it for later use. Then add 90 parts of alcohol into the large mixer, start the mixer to stir, add 100 parts of thermoplastic phenolic resin, stir for about 4 hours, add the prepared thermosetting phenolic resin solution containing coupling agent, and add the prepared Toughening agent and 0.8 parts of plasticizer dioctyl phthalate. After stirring for 3 hours, add 4 parts of urotropine as a curing agent, rinse the container used above with 6 parts of alcohol, add a stirrer and continue stirring for 5 hours, discharge the material and seal it in a barrel to obtain an adhesive for grinding wheel mesh.

Embodiment 3

[0040]According to the raw material composition and parts by weight in Example 3 in Table 1, 1.2 parts of silane coupling agent KH-550 was added to 35 parts of thermosetting phenolic resin liquid, stirred evenly, and placed for later use. Take 1 part of toughening agent polyvinyl butyral and dissolve it in 5 parts of alcohol, fully dissolve it for later use. Then add 100 parts of alcohol into the large mixer, start the mixer to stir, add 95 parts of thermoplastic phenolic resin, stir for about 3.5 hours, add the prepared thermosetting phenolic resin solution containing coupling agent, and add the prepared toughener and 1 part plasticizer dibutyl phthalate. After stirring for 4 hours, add 2 parts of urotropine as a curing agent, rinse the container used above with 5 parts of alcohol, add a stirrer and continue stirring for 5 hours, discharge the material and seal it in a barrel to obtain an adhesive for grinding wheel mesh.

Abstract

The invention relates to an adhesive for grinding wheel meshes and a preparation method of the adhesive. The adhesive comprises 80-110 parts of thermoplastic phenolic resin, 1-6 parts of curing agent, 20-40 parts of thermosetting phenol resin liquid, 60-140 parts of alcohol, 0.5-2 parts of flexibilizer, 0.5-2 parts of coupling agent and 0.5-2 parts of plasticizer. The preparation method includes adding the alcohol into a stirrer, adding the thermoplastic phenolic resin whiling stirring, stirring for 3-4 hours, adding the thermosetting phenol resin liquid containing the coupling agent, the plasticizer and the flexibilizer containing the alcohol after phenolic resin blocks are totally dissolved, stirring for 3-4 hours prior to adding the curing agent, and continue stirring for 4-6 hours to obtain the adhesive. The adhesive prepared by the method can be ready-to-use and ready-to-prepare and is good in stability pollution and mainly used for impregnation of the grinding wheel meshes, pollution and waste are reduced, brittleness of the grinding wheel mashes, strength and adhesive performance are improved, and accordingly wear resistance of grinding wheels is improved, highest rotation speed of the grinding wheel is increased, and service life of the grinding wheel is improved.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof, in particular to an adhesive for a grinding wheel mesh and a preparation method thereof. Background technique [0002] The grinding wheel mesh is the skeleton of the resin grinding wheel, which plays a particularly important role in the strength of the entire grinding wheel and directly determines the quality of the grinding wheel. The grinding wheel mesh is made of grinding wheel mesh cloth coated with adhesive and dried, then punched and laminated with non-woven fabric, black paper and plastic film when necessary. It has excellent tensile strength and flexural resistance. It is a variety of resin Optimal reinforcement base for grinding wheels. The superior performance of the adhesive of the grinding wheel mesh directly affects the service life and wear resistance of the grinding wheel. [0003] The traditional grinding wheel mesh adhesive is made by the manufacturer in a reactio...
